摘要/Abstract

摘要： 使用注水称重法测量药筒容积时，由于注入的液体具有表面张力，会出现液面中间高、边缘低的现象，从而产生测量误差。提出一种基于注水称重法的高精度药筒容积测量系统：采用不同深度的阵列电极测液位，能够克服液体表面张力带来的影响；通过无线传输模块，将由特制电极采集传感信号传输到计算机，并对流量进行控制，以达到精确测量目的。经过系统精度分析，分析结果表明：该系统精度达到了0.01%，满足精度指标要求。

Abstract: A phenomenon that liquid level is low at the edge and high in the middle appears to cause the measuring errors due to the surface tension of the injected liquid when the cartridge volume is measured by water injection weighing method. A high precision measuring system based on the water injection weighing method is proposed. In the proposed system, the array electrodes are used to measure liquid level to overcome the effect of the liquid surface tension. The sensor signal is picked up by a specially made electrode, and then it is transmitted to a computer through a wireless module to control the flow until the cartridge is filled with the water, so as to achieve the purpose of accurate measurement. The accuracy of the system is analyzed. The analysis result shows that the accuracy of the system is up to 0.01%, which meets the requirement of precision index.

Key words: ordnance science and technology, high precision, volume measurement, array electrode, liquid surface tension
